CENTRIFUGAL WASHING MACHINE.

Application filed November 4, 1922. Serial No. 599,035.

To all whom it may concern Be it known that we, DAVID DAY and THOMAS ALEXANDER DAY, residents of the city of Vancouver, in the Province of British Columbia, Canada, have invented. certain new and useful Improvements in Centrifugal. Washing Machines, of which the following is a specification.

Our invention relates to improvements in washing machines which has for its objects I the provision of means for. washing, boiling, rinsing and rough drying clothes in a single device, without handling the clothes in any way throughout the various processes, and

which consists essentially of a perforated container rotatable about a vertical axis and set within a casing having a plurality of vanes disposed upon the floor to direct the washing water from the sides of the casing upwardly into the container, and a means for heating the water whilst the machine is in operation, as will be more fully described in the following specification in which Fig. 1 is a sectional view of the washing machine.

Fig. 2 is a sectional view taken on the line 2-2.

Fig. 3 is a sectional view taken on the line 33.

In the drawings like characters of referefisnce indicate corresponding parts in each The numeral 1 indicates a cylindrical casin having a bottom 2 in' which is set a suit- 35 ab e waste cock 3. The upper edge of the casing is flanged outwardly to form an annular bearing support 4 provided with a ball race 4". 5 indicates a plurality of legs supporting the machine.

6 is a cylindrical container having a bottom 7 with a central aperture 8 therein and perforated side walls 9 which are flanged at their upper edge as at 10 to form a closure between the container 6 and the casing 1 and 48 also to form an annular race 10" opposing the race 4* and from which the container is suspended. Balls 4 coact with the races 42 and 10 to permit of the free rotation of the container 6.

11 indicates a plurality of vertical vanes, (see Fig. 3) radially disposed around ,the aperture 8 of the container which are severally capped with a downwardly dished plate 12.

ea The numeral 13 indicates an overhanging arm mounted upon the casing 1 for the purpose of carrying a motor 14 which is mounted vertically thereon and by which rotary movement is imparted to the container through its shaft 15 and a spider 16 secured at the extremity of its several arms to the flange 10 by bolts 17.

While we have shown a means of driving the machine by a central shaft, it will in some instances be preferred to employ different means therefore without departing from the spirit of the invention.

18 indicates a slightly cone shaped disc of a diameter substantially similar to that of the container 6 resting upon the vanes 20 to form a'false floor which is provided with a central aperture 19 through which the water within the casing is forced upwardly and into the container. 20 (see Fig. 2) indicates a plurality of vanes upon the bottom 2 of the casing 1 which extend inwardly to a point adjacent the centre of they floor, the curve of the vanes being directed against the circular flow of water in the machine, that it may be forced from the periphery of the casing towards its centre.

The numeral 21 indicates a gas ring or other suitable heating device immediately below the casing, whereby the water therein is maintained at a given temperature or brought to a boil, while the machine is'running, audit also serves to cause a more rapid circulation of water through the apertures 8 and 19 thus facilitating the washing of the clothes in the container.

Having thus described the several parts of our invention we will now briefly explain its use.

Soiled clothes are placed in the container 6 and sufiicient soapy water added for the purpose of washing, rotary motion is imparted to the container by the driving means causing the waterto be driven by centrifugal action through the clothes and through the apertured side walls 9 of the container.

Thewater in the casing 1 is caused to surge rapidly in the direction of rotation of the container, the water adjacent the floor 2 being diverted from a rotary flow to an inwardly directed flow by the vanes 20 from thence rising in a-column through the apertures 19 and 8 where it is caught by the vertical vanes 11 and thrown outwardly, thus completing the cycle o'frwater circulation.

The temperature ofthe water is raised to a desired degree bythe heating device 21.

thereby increasing the velocity of the upwardly directed column of water above mentioned.

When the clothes have been .suficiently washed, the suds are drained ofi" by the valve 3 and clean Water used in lieu thereof for rinsing purposes, and when the rinsin operation is completed, it sufices to leave t e machine in operation, draining oil the water and to extract all surplus water from the clothes by centrifugal action.

It will thus be seen that we have invented a simple self contained device in which all processes attendant upon clothes washing may be readily performed without intermediate handling.

What we claim as our invention is: i

In a Washing machine, the combination means? wi 11 the water container-and clothes coninlet, of a sli htly conical plate located 0011-.

centrically within the bottom interspace and having a centre opening in vertical alignment with the inlet opening of the clothes container, and a series of radial vanes located between the conical plate and the bot tom of the water container and curved to direct the Water radially inward.

Dated at Vancouver, B. 0., this 12th day of October, 1922.
